CHARGE SYSTEM FOR SERIES CONNECTED RECHARGEABLE BATTERIES
First Claim
1. A charge system for series connected rechargeable batteries, comprising:
- a power generating unit adapted to receive a voltage input from an AC power source and operable to generate a DC input power based on at least the voltage input;
a charge control unit coupled to said power generating unit, receiving the DC input power from said power generating unit, and operable to generate a charge voltage based on at least the DC input power;
an interface unit connected electrically to said charge control unit and adapted to be connected electrically to each of the rechargeable batteries such that the charge voltage from said charge control unit is supplied to the rechargeable batteries through said interface unit to charge the rechargeable batteries; and
a plurality of detecting units each connected electrically to said charge control unit and said interface unit, each of said detecting units being operable to detect a voltage of a corresponding one of the rechargeable batteries through said interface unit and to generate a feedback power based on the voltage of the corresponding one of the rechargeable batteries upon detecting that the voltage of the corresponding one of the rechargeable batteries is within a predetermined voltage range, and outputting the feedback power to said charge control unit such that the charge voltage is generated by said charge control unit further based on the feedback power from any one of said detecting units.

Abstract
A charge system for series connected rechargeable batteries includes: a power generating unit generating a DC input power based on a voltage input from an AC power source; a charge control unit generating a charge voltage based at least the DC input power from the power generating unit and supplying the charge voltage to the rechargeable batteries through an interface unit; and multiple detecting units each detecting a voltage of a corresponding rechargeable battery through the interface unit, generating a feedback power based on the voltage of the corresponding rechargeable battery upon detecting that the voltage of the corresponding rechargeable battery is within a predetermined voltage range, and outputting the feedback power to the charge control unit such that the charge voltage is generated by the charge control unit further based on the feedback power from any one of the detecting units.
